It's prob on here somewhere but I can't seem to find it but what are the differences between the mini mx races classes? Like what are the restricts between them and what separates the bikes between them? Thanks any help would be great

at vcm there were two classes a and b a was the fast blokes like... untouchable fast whereas b class is the slower riders or 1st timers..
why are there two classes? because the a blokes are so fast there is no point in any slower rider racing to get points so they made two classes to make it more of a fun competition

pretty sure that is correct

 

[lil_fmx_kid]

Ok. I was told usually they have stickers, 88 limited, 10s and 12s or something like that

ahh, it depends what event your at and what numbers of bikes are there and whatnot usually

 

[needapitty]

up here in qld at fort lytton we just have a 12' open class and a 10'' aswell

 

[Phil67]

depends on the series.

In Vic we have VCM thats all 12" a and b grade

We also have

junior boys
senior 10"
senior 12"
senior girls
junior girls
semi auto's, 88's etc, but they usually run in 10"

 

[lil_fmx_kid]

So 10" and 12" is the rear wheel size?

 

[Phil67]

yes correct

 

[lil_fmx_kid]

Thanks Phil. What are the limitations on an 88? I've got after market frame, Mazzi front end. +4 in the rear. How big of a carbi can I go and cam?

 

[mini mullisha]

also long as you have stock head on 88 is fine , forks,frame,swinger , all good for 88 class , cams are allowed and carbie size dosnt matter , though true 88s should only have 18-20mm carbs

 

[Hillz]

what if you have a 70 barrell & head?

 

[lil_fmx_kid]

Oh ok. I've changed the head.

Exactly the info I was hoping for thanks. I've got a different head on my 88 so does that mean I have to race up a class or do I just put the stock head back on?

 

[Georgalis]

Yeah if you've got a bigger head then that would put you into the 10" class

Glad to help man
Yeah haveing race head on you 88 , push bike up into 10" open class. Back in day they had class call'd
88 mod , bean class for you! Only have 10" open ,88 limited northing in middle.

 

[lil_fmx_kid]

So would it be better for me to either go back to a stock head or go the a larger barrel and head to be more competitive

 

[Georgalis]

At the moment with
Lower numbers racing there hasn't been an 88 limited class
It's usually 10" bikes together in one class and 12" bikes together in another class
So I reckon whack ya bigger head on !

 

[lil_fmx_kid]

I'm keen to get out there and have a race then
